Filing lawsuits against PEMEX was not advisable due to the complexity of the situation. The fault does not lie with PEMEX because it was a public finance issue. PEMEX and CFE’s treasuries are run by the Ministry of Finance and companies should understand the risks when they agree to do business with them. The first influencing factor was the drop in oil prices, which changed drastically after many contracts had already been signed. Secondly, the previously strained relationship between PEMEX and the Ministry of Finance negatively impacted the NOC’s ability to make payments. PEMEX has now started to pay providers, focusing its efforts on smaller companies. This causes issues because if the larger companies are not paid there is a chain reaction and they cannot pay their subcontractors.
